Building Beirut Terraces: A Multi-layered Skyscraper

Building Beirut Terraces: A Multi-layered Skyscraper

BEIRUT has a breath-taking new skyscraper; a structure that takes inspiration directly from the rich layers of the city’s culture and tumultuous history.

Designed by Swiss architecture partners Herzog and de Meuron, Beruit’s newest tower is a vertically layered building, that aims to capture the complex
past and bright future of Lebanon’s capital city. The 119-metre structure is part of a wider masterplan to regenerate the area around St George’s Hotel;
the site of a devastating car bomb attack that killed prime minister Rafik Hariri in 2005.

Looking to the future, the modern tower has been created by stacking irregularly sized floor slabs to give the building a unique irregular outline, similar
to the architect’s Jenga-esque 56 Leonard tower in New York.

A SKYSCRAPER OF TERRACES

To construct the skyscraper’s unique form, five modular floors were repeated in different combinations. The varying sized slabs, create an interesting
interplay between openness and privacy that fosters flexible living between inside and outside.

The building’s floor slabs overhang all of its glazed perimeter walls to create large terraces for the apartments whilst providing shading for the residences
below. Perforations in the overhangs modulate light, exposing some areas to sun, while others are cast in shadow.

Beirut Terraces has been designed to enable residents to take advantage of the city’s moderate climate – a factor which has long made outdoor living an
integral part of Beirut's urban culture.

A VERTICAL GREEN BOULEVARD

The trees and plants that are placed on the tower’s expansive terraces add greenery to an otherwise white structure. These plants flow from the terraces
to create a vertical "green boulevard" that connects the residential high-rise with its surroundings.

The planting also serves a practical purpose, acting as a screen, to ensure a degree of privacy for the fully glazed living areas while still permitting
views out to sea.

BUILDING A STAGGERED SKYSCRAPER

Although the building has a complex form its structure is actually relatively simple. The five different floor plates are supported on a central reinforced
concrete core and a regular grid of columns set 14.7 meters apart from each other. Such an approach reduces the extent of structural walls within
the apartments, enabling unique layouts and future flexibility.

The residences are distributed throughout the building, with some set over a single level and others arranged over two-storeys. Each quarter of the
tower has its own lobby with elevators serving no more than two apartments at a time. For improved efficiency, two lobbies share service elevators,
mechanical and electrical risers, and fire escapes. A shared viewing terrace tops the block featuring a spa, pool and sauna. A number of retail
units are arranged along the eastern facade.

Though a combination of a simple structure and staggered floorplates, Herzog and de Meuron have created a living environment that is entirely appropriate
for Beruit’s climate; a multi-layered, vertical community that speaks of the city’s past, while standing as an impressive statement of intent for
its future.
